Is 4.8 shortsighted?

Visual acuity 4.8 is not necessarily myopia.

Visual acuity 4.8 is the visual acuity value measured by logarithmic visual acuity chart, equivalent to 0.6 of international standard visual acuity chart. This is only a test result of visual acuity function, and can not directly determine whether myopia. Because vision is affected by many factors, such as eye disease, lens opacity, etc., vision may also be affected by environment, light, distance and mental factors.

Therefore, whether visual acuity 4.8 is myopia should be combined with their own actual situation, and under the doctor's standard examination to determine. If vision is usually good, sudden vision decline should be timely to the eye examination to determine the cause of vision decline.
